Brake device

Abstract

A brake disc guard is provided inside of a rim of a front wheel and mounted on a knuckle. A caliper is located in a cutout portion formed at a front portion of the brake disc guard. The caliper is supported through a caliper bracket to the knuckle. A large-diameter portion is formed at an upper front end portion of the brake disc guard. The large-diameter portion extends so as to cover the upper side of the caliper bracket and the caliper. A scraper is formed at the front end of the large-diameter portion so as to be bent radially outwardly. The spacing a between the rim and the scraper is set to be the smallest. The dirt deposited on the rim is scraped off by the scraper, so that the dirt separated from the rim is prevented from falling onto the caliper.

1. A brake device having a disc brake provided inside of a rim of a wheel and supported on a knuckle and a cover member formed of resin for covering a disc of said disc brake, said cover member being provided inside of said rim and supported on said knuckle, wherein said cover member includes a flange projecting axially and outwardly from said cover member towards a wheel disc with a scraper including a free end projecting radially and outwardly from said knuckle, said free end of said scraper projecting radially outwardly and being at a predetermined angle relative to said flange so as to come close to said rim for preventing debris from reaching said disc. 
     
     
       2. The brake device according to  claim 1 , wherein the flange extends in a circumferential direction along the outer circumference of said disc and projects sideward so as to cover the outer circumference of said disc, said scraper being formed integrally with said flange. 
     
     
       3. The brake device according to  claim 2 , wherein the cover is a brake disc guard that includes an outer circumference of an upper portion that continues through a step portion to an outer circumference of a lower portion of the brake disc guard, said step portion being formed in a vicinity of a lower end of the flange with the lower portion being smaller in diameter relative to the upper portion. 
     
     
       4. The brake device according to  claim 3 , wherein a spacing between the scraper and the inside of the rim is smaller relative to the spacing between a large diameter portion and the inside of the rim. 
     
     
       5. The brake device according to  claim 4 , wherein a spacing between the flange and the inside of the rim is greater relative to the spacing between the large diameter portion and the inside of the rim. 
     
     
       6. The brake device according to  claim 5 , wherein a spacing between the outer circumference and the inside of the rim is greater relative to the spacing between the flange and the inside of the rim. 
     
     
       7. The brake device according to  claim 6 , wherein the spacing between the large diameter portion and the inside of the rim is substantially equal to the spacing between the outer circumference of the upper portion and the inside of the rim. 
     
     
       8. The brake device according to  claim 2 , wherein said scraper and a part of said flange extend so as to cover the upper side of a caliper and a part of a caliper bracket. 
     
     
       9. The brake device according to  claim 2 , wherein said flange extends along said cover member and projects a predetermined distance therefrom starting with a lower end that initiates a projection from said cover member to an upper portion that extends a maximum projection from the cover member. 
     
     
       10. The brake device according to  claim 1 , wherein said cover is a brake disc guard and said brake disc guard includes a cutout portion and further including a caliper operatively connected to said knuckle for selectively being brought into engagement with said disc, said caliper being disposed within the cutout portion of said brake disc guard. 
     
     
       11. A brake device comprising:
 a disc brake adapted to be provided inside of a rim of a wheel and supported on a knuckle; 
 a cover member for covering a disc of said disc brake, said cover member being provided inside of said rim and supported on said knuckle; and 
 a flange projecting axially and outwardly from the cover member towards a wheel disc with a scraper including a free end projecting radially and outwardly from the knuckle, said free end of the scraper projecting radially outwardly and being at a predetermined angle relative to the flange and adapted to be disposed close to said rim for preventing debris from contacting said disc of the disc brake. 
 
     
     
       12. The brake device according to  claim 11 , wherein the flange extends in a circumferential direction along the outer circumference of said disc and projects sideward so as to cover the outer circumference of said disc, said scraper being formed integrally with said flange. 
     
     
       13. The brake device according to  claim 12 , wherein the cover is a brake disc guard that includes an outer circumference of an upper portion that continues through a step portion to an outer circumference of a lower portion of the brake disc guard, said step portion being formed in a vicinity of a lower end of the flange with the lower portion being smaller in diameter relative to the upper portion. 
     
     
       14. The brake device according to  claim 13 , wherein a spacing between the scraper and the inside of the rim is smaller relative to the spacing between a large diameter portion and the inside of the rim. 
     
     
       15. The brake device according to  claim 14 , wherein a spacing between the flange and the inside of the rim is greater relative to the spacing between the large diameter portion and the inside of the rim. 
     
     
       16. The brake device according to  claim 15 , wherein a spacing between the outer circumference and the inside of the rim is greater relative to the spacing between the flange and the inside of the rim. 
     
     
       17. The brake device according to  claim 12 , wherein said scraper and a part of said flange extend so as to cover the upper side of a caliper and a part of a caliper bracket. 
     
     
       18. The brake device according to  claim 12 , wherein said flange extends along said cover member and projects a predetermined distance therefrom starting with a lower end that initiates a projection from said cover member to an upper portion that extends a maximum projection from the cover member. 
     
     
       19. The brake device according to  claim 11 , wherein said cover is a brake disc guard and said brake disc guard includes a cutout portion and further including a caliper operatively connected to said knuckle for selectively being brought into engagement with said disc, said caliper being disposed within the cutout portion of said brake disc guard. 
     
     
       20. A brake device comprising:
 a disc brake adapted to be provided inside of a rim of a wheel and supported on a knuckle; 
 a cover member for covering a disc of said disc brake, said cover member being provided inside of said rim and supported on said knuckle; and 
 a flange projecting axially and outwardly from the cover member towards a wheel disc with a scraper including a free end projecting radially and outwardly from the knuckle, said free end of said scraper projecting radially outwardly and being at a predetermined angle relative to the flange and adapted to be disposed close to said rim for preventing debris from contacting said disc of said disc brake, 
 wherein said flange extends in a circumferential direction along the outer circumference of said disc and projects sidewardly along said cover member and projects a predetermined distance therefrom starting with a lower end that initiates a projection from said cover member to an upper portion that extends a maximum projection from the cover member.
